Conventional anchor is all make prismatic shapes, and uplift resistance mainly provides by anchoring body and Rock And Soil, and this value is less under normal circumstances, and especially in soft clay area, because geological conditions itself is poor, anchoring effect is also corresponding undesirable.The research core content of anchoring improves in anchor structure and construction technology, to strengthen anchoring effect both at home and abroad at present.But a lot of method strengthening anchoring effect not only complex procedures and also cost higher.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides the multistage increasing resistance anchor pole that a kind of structure is simple, easy and simple to handle, cheap.
For achieving the above object, the utility model adopts following technical proposals:
A kind of multistage increasing resistance anchor pole, comprise the body of rod, described body of rod front portion is fixed with body of rod scotch, described body of rod rear portion is connected with jacking bar, body of rod outer cover between described body of rod scotch and jacking bar is equipped with the multiple from enlarging device of hollow structure, described jacking bar can promote to move from enlarging device, described is cone structure from enlarging device front portion, be hollow connecting rod from the centre of enlarging device, rear portion is along being provided with multiple key from the circumferencial direction of enlarging device, described first is connected with body of rod scotch from the cone structure of enlarging device, last is connected with jacking bar from the key of enlarging device, the adjacent key from enlarging device is connected with cone structure, the afterbody of the described body of rod is provided with fastening devices.
The described body of rod is solid construction, and rear end is provided with screw thread.
Described jacking bar is hollow structure, and jacking bar front end is cone structure, and rear end is provided with jacking base, and centre is hollow connecting rod.
Described fastening devices is rotated by the screw thread of body of rod rear end and the body of rod fixes.
Described key is fitted on the body of rod when being in unexpanded mode from enlarging device, and key is in open configuration when holding out against another from enlarging device from enlarging device for one.
Thick rear end, described key front end is thin, facilitates cone injection.By the promotion of jacking bar and the stop extruding of lever front end body of rod scotch, realize the automatic expansion from enlarging device, fixed the position of jacking bar by fastening devices, realize the body of rod and increase being permanently fixed of resistance state.
The utility model device is applicable to ground anchorage, can realize the automatic expansion of anchor pole from the design of enlarging device, increases the contact area of anchor pole and rock mass and cement grout, improves its anti-pulling ability.
The utility model solve in the past common bolt also slurries and country rock contact area little, a difficult problem for anti-pulling ability, the utility model device has following beneficial effect:
1) device has dismantled and assembled property, by change from enlarging device hollow connecting rod size and the body of rod nested from enlarging device quantity, change and increase resistance progression, convenient actual for engineering, take multiple increasings to hinder rank setting;
2) stress applies simple, and by the precession of bolt, realize the expansion from enlarging device rear end, operation is simple and feasible, meets request for engineering action;
3) thick rear thin design before the rice font key of enlarging device rear end, facilitates the injection of tapered end, and the key simultaneously opened can insert country rock easily or surrounding soil is inner, increases the frictional resistance of the body of rod and the soil body;
4) each ingredient of device is simple, can realize batch and produce fast, meet batch production, mass production requirement.
